摘要： A focus controller for focusing a light beam and positioning the focused light beam onto a signal recording layer of a signal recording media is disclosed. The controller comprises a light beam focusing means having a numerical aperture of 0.6 or more; a focus controlling means for positioning the light beam focused by the light beam focusing means onto the signal recording layer of the recording media; and an offset adjusting means for adjusting an offset between the focused light beam positioned by the focus controlling means and the signal recording layer of the recording media. The controller positions the light beam focused by an objective lens onto the signal recording layer of a recording media; moves the objective lens within a predetermined optical-axial range, detects an amplitude of a signal read from the recording media at either end of the optical-axial range, and adjusts an offset between the focused light beam positioned by the objective lens and the signal recording layer, depending on a difference between the amplitudes of the detected reproduced signal.
